Check Digit Verification of cas no
The CAS Registry Mumber 421-71-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 421-71:
(5*4)+(4*2)+(3*1)+(2*7)+(1*1)=46
46 % 10 = 6
So 421-71-6 is a valid CAS Registry Number.
